SAFETY AND LIKE PIN.

Application led August 7, 1922. Serial No. 580,072.

T 0 all whom t may concer/n.'

' Be it known that I, OSCAR E. RioHARDsoN, a United States citizen, residing in Naugatuck, New Haven County, Connecticut, have invented the following described ,Improvements in Safety and like Pins. l

The object of this invention is to'reduce the possibility of accidental opening of safety pins, clasp pins, brooches, ba-rrettes and the like, without substantial or any increase in the cost of their manufacture. y

'ln the accompanying drawings the inven tion is illustrated in its preferred form as applied to an ordinary safety pin, Fig. l being al perspective and Fig. 2 a side elevation, both in large scale and the latter showing the pin in use.V f

- It will be seen that the pin is formed as usual of a pair of relatively movablelimbs united by a spring coil or hinge at one end, and thatthe pointed or--penetrating limb l, or pin proper, is received Within a seat 2 in the head which is preferably a sheet-metal cap secured tothe other limb or the body part of the pin, and from which it can be removed by pressing the pin toward the other limb or body part and then, or simul-Y taneously shifting it sidewise. The invention is applied to such a safety pin by form ing a notch in the cap adjacent to the bottom of the pin seat, so that the ren'iaining part of the cap or scat forms a shoulder or shoulders, marked 3 in the drawing. This shoulder, or each of these shoulders, is Substantially inflexible or rigid. It is spaced inward with reference to the pin. When the pin has been pushed through the material 4 in which it is used, the picked `up part 5 of said material, especiallyif it is a full pickup, enters the space between the pin and the shoulder or shoulders 3 and thereby constitutesan obstruction to the exit of the pin from its seat, as will be apparent in the drawing, and such obstruct-ion is found to form a most effective means of guarding against accidental opening.

rlhe pin is of the outwardly seating type,

'the pin seat being disposed outward'of the seated pin which is pressed against the seat by its spring. The abutment means is blunt and cannot pierce the cloth, but faces the right side of the picked-up material, i. e. the side vfrom which the pin is being operated when the pin is in use, thus blocking movement of the pin inward from its seat, the eXit-blocking effect being produced by abutment means 3. It will be observed that the particular location or mounting of 'the shoulders is immaterial so long as they form an abutment facing the right side of the picked-up material and adapted to sustain thepicked-up material against pressure eX- erted on it by thefpin in the opening direction. It is however desirable to accomplish this result without placing any part of the pin structure in the path of pin movement from the pin seat,'and it is a distinctive and advantageous, although not indispensable, feature of the invention, in its lprefer-red forms and in association with other described structurall arrangements characteristie of the invented pin, that the pin exit is Vnot obstructed except .by the picked-up material, the cloth-sustaining means, or rundercut portion with which the end of the cap facing the picked-up material is provided, and which furnishes a space adjacent the seated pin to receive the material, being out of the line of pin movement fro-1nv the pin seat. The pin 'ls thus freely releasable von disengagement of the material from the undercut part of the cap. It will be observed also that such material-sustaining member or members can be applied to any design or construction of outwardly closing clasp pin or the like so long as the same comprises a seat from which the pin or penetrating limb is normally removable by inward movement transverse to its own length. It is preferredv that the abutment means shall be constituted of twov proximate members or shoulders flanking the path through which the pin must be moved in order to escape from the seat, because this presents the most positive means of supporting the picked up material against the pressure ofthe pin. In the case of ordinary safety pins, the shoulders 3 are mostJ conveniently formed when stamping the cap from the sheet stock from which it is made, and they are preferably given a slight outward slope tending to retain the material in obstructing position. The word undercut used in certain of the claims has no reference to this outward slope and carries no implication as to any slope or angle. As will be apparent, the pin may be readily opened when desired by manipulating it so as to disengage the material from the shoulders.

Claims- 1. A safety or like pin of the outwardly seating type comprising a head having a pin seat, a main limb, and a pointed limb, the latter bei-ng springepressed outward or away from the main limb and against said seat, and abutment mea-ns located yopposite the part of the pointed limb adjacent the pin seat and co-operating with the pin seat to form a pat-h or space adapted to permit the free and easy removal of the pointed limb in the absence of pinned fabric between said abutment means and said limb part, but to block removal of the pointed limb when pinned fabric is between the. abutment means and said limb part.

2. A safety or like pin according to claim l in which the head is a sheet metal cap having the abutment means, which provides fabriccontacting surface at each side of the pointed limb to contact with the side of the picked-up fabric from which the pin is operated and thus support the pinned fabric atliwart the path of the pointed limb from its seat, thereby preventing release of the pointed limb when pinned fabric is present but permitting` free and easy removal of the pointed limb in the absence of pinned fabric between said abutment means and said limb art.

p 3. A safety or like pin comprising a main limb having a pin seat and an outwardly inclined shoulder or shoulders adapted to retain and sustain the picked up material in position blocking the enitI of the pin from its seat.

4. A safety or like pin of the outwardly seating type having a main limb providing a seat for the pointed limb disposed outward thereof and a pair of blunt cloth-obstructing abutment members flanking the pin and between which lies its exit path, and which provide means for sustaining the picked-up material athwart the exit path of the pin.

5. A safety or like pin comprising a main limb carrying a sheet metal cap having a pin seat and notched to provide a space between the seated pin and the cap facing the right side of the cloth and receiving the picked-up material thereby enabling the latter to occupy a position in which it blocks thepin exit.

6. A safety or like pin comprising a main limb carrying a cap providing a pin seat and having its end facing the right side of the picked up material provided with an undercut portion to permit entry of the picked-up material between the seated pin and the said undercut portion of the cap and consequent obstruction by said material of the exit of the pointed limb from its seat.

7. A safety or like pin of the outwardly seating type having al main limb carrying a sheet metal cap provided with a pin seat disposed outward of the pin and having blunt cloth-sustaining means located on the pin seat side of the cap and opposing the right side of the cloth.

8. A safety or like pin having a main limb carrying a point-protecting cap forming a seat for the pointed limb and having a pair of shoulders, one at each side of the pin, spaced inward with reference thereto, and leaving the pin exit unobstructed save for picked-up material sustained by said shoulders in position to block the pin exit.

9. A safety or like pin of the outwardly closing type having a main limb carrying a point-protecting cap forming a seat for the pointed limb disposed outward thereof and having an undercut portion spaced inward with reference 'to the pinto permit entry of the picked-up material between the pin and said undercut portion by which it is sustained in the exit path of the pin.

10. A safety or like pin of the outwardly seating type having a main limb providing a seat for the pointed limb disposed outward thereof and a pair of blunt cloth-obstructing abutment members flanking the pin and between which lies its exit path, the abutment faces of said members being spaced inward with reference to the pin and thus leaving cloth-receiving space for the picked-up material and providing means for sustaining it athwart the exit path of the pin.

ll. A safety or like pin of the outwardly seating type having a main limb, a sheet metal point-protecting cap carried thereby and having a seat for the pointed limb disposed outward thereof and having a pair of blunt cloth-obstructing members flanking the pin and between which lies its exit path, the abutment faces of said members being spaced inward with reference to the pin and thus leaving cloth-receivng space for the picked-up material and providing means for sustaining` it athwart the exit path of the 12. A safety or like pin comprising amain limb carrying a point-protecting cap providing a pin seat disposed outward of the pin, and cloth-obstructing means facing the right side of the cloth, located out of the line of eXit movement of the pin from its seat and spaced inward from the seated pin to leave room for the materiall to enter between the pin and said means and liel of the line of exit movement of the pin from athwart the pin exit. its seat and leaving the pin exit free when 18. A safety or like pin comprising a the picked-up material is removed from obl0 pointed limb and a main limb carrying a struoting position. 5 sheet metal cap provided With a pin seat In testimony whereof, I have signed this for the pointed limb located exterior therespecification. to and having cloth-sustaining means` out OSCAR E.
